Question: Two disks are oriented on parallel planes separated by a distance of 10 in., as shown in the accompanying figure. The disk to the right

Two disks are oriented on parallel planes separated by a distance of 10 in., as shown in the accompanying figure. The disk to the right is 4 in. in diameter and is at a temperature of 500°F. The disk to the left has an inner ring cut out such that it is annular in shape with inner and outer diameters of 2.5 in. and 4 in., respectively. The disk surface temperature is 210°F. Find the heat exchange between these disks if a. they are black b. they are gray Îµ₁= 0.6, Îµ₂= 0. 3

4 in. 2.5 in. 10 in. 2.
